Variables in the index URL field

[jsbien]

I would be happy to use something like "$tom1" instead of e.g.

http://korpusy.klf.uw.edu.pl/djvus/linde-t/01/index.djvu

This would allow easily switch between a remote site and a local copy etc.

Can it be done simply with the mechanism used for #262?

[Michał Rudolf]

How should it work? What will be the source of variations and where they will be used? Is this for index URL? Or what?

[jsbien]

Yes, it's for index URK. The idea is that the master index whould not have the full address, but something like $tom1/index.djvu?djvuopts&page=131&zoom=width&showposition=0.649,0.721&highlight=3000,1747,183,76.

By default it should be expanded to https://djvu.szukajwslownikach.uw.edu.pl/linde-t/01/index.djvu?djvuopts&page=131&zoom=width&showposition=0.649,0.721&highlight=3000,1747,183,76, but the user should be allowed to overwrite the default and get something like file:///usr/share/Linde/Linde2wyd/01/index.djvu?djvuopts&page=131&zoom=width&showposition=0.649,0.721&highlight=3000,1747,183,76.

So, indeed the idea to replace parts of URL will work. But maybe instead of variables we can just use parts of URL? For example: https://djvu.szukajwslownikach.uw.edu.pl/linde-t/ = file:///home/someuser/djvu/linde/

And all the external links will be replaced with local copies.

[jsbien]

OK, this will do.

Tested on

http://poliqarp.wbl.klf.uw.edu.pl/extra/linde=http://djvu.szukajwslownikach.uw.edu.pl/linde

[jsbien]

http://korpusy.klf.uw.edu.pl/djvus/linde-t/01/=file:///home/jsbien/cachedLinde/1/

gives

QDjVuDocument::setUrl: cannot create
QDjVuDocument::setFileName: cannot read file

It was just a typo in the path.
